I think for this file using only -mcmodel=large makes more sense.

Given the proposed option (-fstatic-pie) is not kernel specific, the TLS is not
needed. What do you think about disabling optimization like switch folding [1]?
It seems to exist only to remove relocations that is not even needed in a
classic -fPIE (or -fstatic-pie) scenario.
